I'm pretty sure of it. My troll has the one I got from najena alt as a souvenier.

I call it najena alt because when you zoned in during the revolving 4 day event across all the servers (it was on different servers at different times) it said "zoned into najena_alt" instead of najena.

I will look at their stats then mail in a screenshot if it is 9 ac. The rubicte in najena alt was not exactly the same as that in cazic.
